Description

Everyone who knows requirejs knows that every page that needs modular development must have an entry js file for module configuration. But now there is a very embarrassing problem. If there are many pages, then there will be many entry files corresponding to the data-main. In theory, this is okay, but when you use grunt to merge and compress it later, there will be many entry js. Although this entry js compresses all the configured module contents, there are actually many entries in the merged and compressed files of each entry. Overlapping codes, so taking this into consideration, I thought of unifying all the entry files and using one. When the time comes, using grunt to merge and compress, there will only be one entry file, which is also very convenient.

Implementation principle

1. The page introduces requirejs and sets the attributes of id and current page information

<script></script>

2. Write require.config.js according to Different pages initialize different page information

/**
 * 1、所有页面使用公共的require配置
 * 2、根据current-page去加载相应地模块，不需要的模块不要去加载
 * 3、每个模块都要按约定去对外暴露一个init的初始化方法，用于页面信息加载时间监听
 * 
 */require.config({　
    urlArgs: "ver=1.0_" + (new Date).getTime(),　　　
    paths: {　　　　　　"jquery": "/res/js/base/jquery-1.11.3.min","vue":'/res/js/base/vue.min',"common": "/res/js/widgets/common"},
    shim: {'scroll': {　　　　　　
            deps: ['jquery'],
            exports: 'jQuery.fn.scroll'　　　　
        },'vue':{
            exports:'vue'},'common':['jquery']
    }
});


require(["jquery"], function ($) {
    require(["common"], function (common) {var currentPage = $("#current-page").attr("current-page");var targetModule = $("#current-page").attr("target-module");if (targetModule) {// 页面加载完毕后再执行相关业务代码比较稳妥$(function () {
                require([targetModule], function (targetModule) {// 不要在这里写业务代码//全部统一调用init方法//也就是每个模块都暴露一个init方法用于事件监听，页面内容加载等                    targetModule.init(currentPage);
                });
            });return;
        }
    });
});

3. Define the module and implement the initialization init method for event monitoring and page information initialization

define(['jquery', "common"], function ($, common) {　　　　var newCtrl = {};
    newCtrl.init = function (page) {
        common.info("开始初始化页面信息");
    };
    newCtrl.login = function () {};return newCtrl;
});

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript: Exploring the Versatility of a Web LanguageApr 11, 2025 am 12:01 AM

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The Evolution of JavaScript: Current Trends and Future ProspectsApr 10, 2025 am 09:33 AM

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
